Description

[Detailed description of the invention] "Industrial application field" This invention is a material feeding device that is attached to a press and supplies blanks to the press.The top surface is pushed up to an approximately constant height in order to take out blanks one by one from the top. A magnetic separator that separates the blanks one by one and a holder that holds a certain amount of blanks when replacing the blank stack are attached to the upper outer periphery of the blank stack (loaded blanks). The present invention relates to a separator plate apparatus which includes a separator plate and which is removably secured to a separator base.

"Prior Art" Conventionally, in a material supply device, a device for removably fixing a separator plate to a separator base was separated into two positioning pins installed upright on the separator base 1, as shown in Fig. 7. It was positioned by fitting the holes in the container plate 3 and fixed with four bolts 4.

``Problems to be solved by the invention'' In the conventional device described above, when attaching and detaching the separator plate 3, four bolts 4 must be removed and attached, which takes a lot of time and requires the use of a crane. It is necessary to hang a wire around the eye bolt 5. This operation is necessary when a blank with a different shape from the blank handled in the press is to be handled in the next processing, and the separator base 1 is moved to a position away from the material supply stage. Therefore, even if the crane is easy to operate, in workplaces where the crane is used frequently, the operator may have to wait for the crane, which often reduces the efficiency of press work.

The purpose of the present invention is to eliminate these drawbacks, to provide a separator plate that can be easily attached and detached from the separator base, and that can be manually carried in and out on an auxiliary trolley, reducing man-hours and improving efficiency. The goal is to provide equipment.

"Means and effects for solving the problem" The structure of the present invention is to provide a guide on the upper surface of the separator base that guides both sides of the separator plate in a direction perpendicular to the moving direction of the separator base, and A roller that rotates while receiving the bottom surface of the plate is embedded in the top surface of the separator base, and the separator plate carried in along the guide hits and stops at a fixed position, and an abutting block that engages with the upper part of the leading edge of the separator Lock pins were provided on both sides of the base, and on the guide on the carry-in side of the separator plate, which protruded and retracted toward both sides of the separator plate and engaged and locked with the upper rear edge of the separator plate. Since the separator base moves on rails installed on the floor, it is at the same height as the separator base, has rollers on the top surface for carrying in and out the separator plate, and uses an auxiliary trolley that runs on the floor. A feature is that the separator plate can be easily carried in and out manually by approaching the side of the separator base in the moving position.

Embodiment In FIGS. 1 to 4, the structure of a separator plate device 6 according to the present invention is shown. The separator base 7 is provided with legs 8, 8 on both sides in the direction of movement, which have wheels at the lower end and run on rails, which will be described later, and on the upper surface, side surfaces of separator plates 9 are provided on both sides in the direction perpendicular to the direction of movement. Guides 10, 10 for guiding are provided. The separator base 7 has a U-shape as shown in FIG. The guides 10, 10 are divided into two parts: a short guide 10a on the U-shaped open entrance side, and a long guide 10b on the opposite side. This is due to production reasons and has no special meaning. Guide 1
Three rollers 11 each are embedded in the separator base 7 on the inner side. Also, abutment blocks 12, 12 are installed on the guides 10, 10 to abut and stop the front edge of the separator plate 9 that has been carried in, and to engage with the upper part of the front edge to prevent it from coming off upward.
It is located near the inside of the The guide 10a protrudes and retracts toward the side surface of the separator plate 9, and engages with the upper rear edge of the separator plate 9 to abut the block 1.
A locking pin 13, 13 is provided which cooperates with 2, 12 to lock it in place.

The lock pin 13 is attached to the guide 1 as shown in FIG.
0, has a handle 13a, a groove 13b on the lower surface engages with a rotation stopper 14 provided on the guide 10a to prevent rotation, and has two grooves 13c on the outer periphery,
The guide 1 is biased toward one groove 13c and movable.
The protrusion/retraction position is determined by engaging with an engagement ball (not shown) provided at 0a. Lock pin 1 shown in the figure
It engages with the upper rear edge of the separator plate 9 at the protruding position 3, and locks the separator plate 9 so that it does not move forward or upward.

The separator plate 9 has a picture frame shape, and the required number of magnetic separators 15 and holders 1 are arranged inwardly on the upper surface of each side.
6 and 2 facing each other along the outer periphery of the blank 17.
We have set up groups for each group.

In FIGS. 5 and 6, the construction of a material supply device 18 with a separator plate arrangement 6 is shown. In these figures, one magnetic separator 15 and one holder 16 are shown on the separator plate 9 for convenience. Two rails 19, 19 are installed in the front and back direction of the press centering on the material supply stage shown by arrow A.
is installed on the floor, and blanks 17 are loaded at two locations on a trolley 20 that runs on the inside of the rail 19, and when one blank 17 is in material supply stage A, it is used to load blanks 17 on the other. be done. Two separator plate devices 6 are provided that run along the outer periphery of the rail 19, straddling the cart 20 and the loaded blanks 17, one of which is placed on the material supply stage A.
During use, the other end is converted into a separator plate 9 to which a magnetic separator 15 and a holder 16 are attached in accordance with the shape of the blank 17 to be handled next.

A lifter 21 is provided below the material supply stage A, and lifts up the blanks 17 loaded on the trolley 20 to a certain height.
5, the suction tool 22 provided above is moved up and down to take out the sheets one by one, and the steps are the same as in the conventional method, such as feeding the sheets to the press 23 via an intermediate conveyance device (not shown).

When the separator plate device 6 replaces the separator plate 9 at the end of its travel on the rail 19, an auxiliary trolley 24 shown in FIG. 5 is used. The auxiliary cart 24 has wheels 25 that run on the floor, and on its upper surface there are rollers 26 that rotate while receiving the lower surface of the separator plate 9, and a stopper 2 that stops the separator plate 9 that has been carried out.
7. The separator plate 9 can be manually moved onto the auxiliary truck 24 by moving the auxiliary truck 24 to the position shown by the dashed line in FIG. Can be moved. Conversely, the separator plate 9 that has been serviced is transferred from the auxiliary trolley 24 to the separator base 7.
The separator plate 9 can be locked by carrying the separator into the separator plate, stopping it by abutting against the abutment block 12, and pushing in the lock pin 13 from the left and right sides.

"Effects of the Invention" As is clear from the above explanation, according to the present invention, the separator plate can be locked to the separator base with a single touch, and the separator plate can be unlatched and manually transported to the auxiliary cart. On the other hand, it can be transported in the opposite direction, making the work easier. Also, since no crane is used, there is no loss of efficiency due to waiting for a crane. The practical effects and benefits are great.
